The development, construction and operation of a novel energy storage facility (Demonstrator) is a central project of the Bavarian Hydrogen Center. The system is essentially based on the Liquid Organic Hydrogen Carrier (LOHC) technology developed at the Friedrich-Alexander-Universität Erlangen-Nürnberg.
In this system hydrogen is generated via electrolysis by means of surplus renewable energy (for example, from a photovoltaic system) and stored chemically (Hydrogenation: hydrogen loading) in a liquid compound. These compounds can be stored in a conventional fuel tank at ambient conditions. When required the hydrogen can be released (Dehydrogenation: hydrogen unloading) and converted into electricity using a fuel cell. This concept will also allow the safe and efficient storage of renewable energy over a longer period of time.
A storage facility will be built and installed in Erlangen as a demonstrator during the course of this project. The scope of the system is based on the storage of regenerative energy from a detached house (photovoltaic system) and the year-round supply of electricity. Besides supplying the house with electricity, the heat generated can be used to heat the house.
The LOHC Demonstrator consisting of a loading and unloading system is currently under development.
